SPECIFIC CHARACTER. 



Body and under Wings white, firft Wings green, with two oblique 

 arrow lines of pale yellow. 



We pofTefs two fpecies of the Green Silver Line; one Phalaena 

 Prafinana, of Linnseus ; the fecond unknown to that author ; but fincc 

 defcribed in the Species Infeclorum of Fabricius. Thofe two fpecies 

 nearly refemble each other, are both taken from the Oak, and are 

 diftinguifhed only in fome few particulars, the Scarce Silver Line has 

 its Superior Wings of a plain pea-green, with two ftripes of feint 

 yellow, the Body and inferior Wings are of an immaculate white. 

 But the Common Silver Line is more variegated in its colour, having 

 a dafh of a paler hue between each Silver Line, and an orange or 

 crimfon border. The Scarce Silver Line is taken in July, in woods. 



Note, Fabricius appears to have changed the name of this Infect in 

 his Spec Inf. for in the Syjlem Entom. he calls the common Silver 

 Line Prafinana, the fame as Linnseus does, which in the Spec he has 

 altered to Fagana.
